What is happening:

1. Lets trigger any notification event, other then raid score. For example EVENT_CAMPAIGN_QUEUE_JOINED:
   

   EVENT_MANAGER:RegisterForEvent(self.notificationManager.eventNamespace, event, self.pushUpdateCallback)

   translated to global reference it is:
   

   EVENT_MANAGER:RegisterForEvent("KeyboardNotifications", EVENT_CAMPAIGN_QUEUE_JOINED, NOTIFICATIONS.providers[3].pushUpdateCallback)

2. NOTIFICATIONS.providers[3].pushUpdateCallback
   

   provider.pushUpdateCallback = function()
       provider:PushUpdateToNotificationManager()
   end

3. NOTIFICATIONS.providers[3]:PushUpdateToNotificationManager()
   

   function ZO_NotificationProvider:PushUpdateToNotificationManager()
       self:BuildNotificationList()
       self.notificationManager:RefreshNotificationList()
   end

4. NOTIFICATIONS.providers[3].notificationManager:RefreshNotificationList() == NOTIFICATIONS:RefreshNotificationList()
   

   function ZO_NotificationManager:RefreshNotificationList()
       self:ClearNotificationList()
       self:BuildNotificationList()
       self:FinishNotificationList()
   end

5. NOTIFICATIONS:BuildNotificationList()
   

   function ZO_NotificationManager:BuildNotificationList()
       for i = 1, #self.providers do
           self.providers[i]:BuildNotificationList()
       end
    
       --rest of the original code
    
   end

6. NOTIFICATIONS.providers[10]:BuildNotificationList() - NOTIFICATIONS.providers[10] is an instance of ZO_KeyboardLeaderboardRaidProvider

As you can see raid score notification will be eventually added to the list even if you unregister update events.
